(1) Introduction
Confucius said, "Learning without thinking is useless." It can be seen how important it is to be diligent in thinking for knowledge. In fact, people should pay attention to thinking in all activities. Only by deep thinking can we make new discoveries, generate creative inspiration, sublimate rationality and avoid many avoidable mistakes.
Therefore, we should learn to think hard and not be lazy.
(2) factual arguments
The proposition of "continental drift theory"
The famous theory of continental drift was put forward by Wei Gena, a German geophysicist and meteorologist. On the map, he found that the right-angled convex part of the eastern end of Brazil, which tore the west coast of South America, coincided with the concave part of the east coast of Cameroon, Africa, and almost every convex and concave part of the Brazilian coast corresponded to every concave and convex part of the African coast. He mused: If two continents are moved and brought closer, then the two parts coincide. Thinking of this, his heart lit up: "These two continents may have been one."
Later, after a long-term study, through geophysical, geological, paleontological and paleoclimatic arguments, the famous "continental drift theory" was put forward. He believes that the earth continent was originally a whole piece, which began to split about 300 million years ago and moved to the east, west, north and south, and later became what it is now.
Later, new scientific discoveries further proved his theory.
Weiler's regret
/kloc-The German chemist Willer in the 0/9th century was an accomplished scientist who discovered two elements, aluminum and beryllium. But he also has regrets. Once, when he was studying ore, he found a chemical substance. Without thinking deeply, he arbitrarily concluded that it was metallic chromium. Soon, the Swedish physicist and chemist Shaw Sturm also encountered this compound. He didn't let it go easily, but conducted in-depth thinking and research, and finally found that this metal is vanadium.
When Wheeler learned about it, he regretted it. Because of my carelessness and lack of serious thinking, I lost a good opportunity for scientific discovery.
